WATER-CLOSET.

I 7 Application filed June 4,

To all whom it mag concern:

Be it known that I,-WINFI'ELD E. HINS- DALE, a citizen of the UnitedStates, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Water- Glosets, of which the following is a specification. o

My present invention pertains to improvements in water-closets, and more especially to closets of the siphon jet type.

The invention is directed particularly to improvements in existing types of siphonjet water-closets, and has for one of its objects the incorporation, integrally with the bowl and general closet structure, of avent duct of large area and, at the same time, to retain a symmetrical shape andto avoid-distortion of the complete closet by the incorporated chambers and water-ways or passages.

In designing such a structure, it should be borne in mind that certain features in common use, such as the means provided for attaching the seat, have become more or less staple or standardized, and the fact that makers of special seats have'adopted certain and fixed measurements makes it imperative that such a design conform to the trade requirements in order to obviate the necessity of'pr'ovidin'g special trimmings and consequently enhancing the cost thereof." Furthermore, itis desirable, if in-fact not necessary, that little, if any, departure be made fromwhat has grown, by years of use andthe practice of all makers, to be the standard measurement of a .closet, both as to height and width. a

A still furtherobject of the invention re sides in the provision of special waysfor the introduction of the water into the flushing rim and to the jet opening; alsointhe .pro- 7 vision of special water ducts or openings for flushing the walls 'of the ventduct.

The arrangement of the channels or con duits which convey the waterto the flushing rim is such that all the contained air in the water passages or conduits above the waterlevel in the bowl will be driven ahead of the falling water from the flushingdevice, without in any wa mixing said confined air with the followlng or advancing water,;thus eliminating all nolse caused by the mixing of air and water under pressure.

V vent duct and the necessarv water ways or channels within the confines of a standard closet, changes must .be made inthe water ways, both asto inlet and outlet, and that the vent ducttitself mustbe kept below the plane ofthe rim of the bowl until well. clear of the portion ofthecloset that is intimate Two embodiments of the. invention are disclosedin the annexed drawings where- 1n,+-

a Figure 1 is a vertical longitudinal sectional view of the'closet having a local or rear vent of large area;

Fig. 4 a transverse vertical sectionalview taken on the line IV-IV of Fig. 1; V

Fig. 5 a vertital longitudinal sectionofa closet embodying the invention but omitting I the local vent.

Referring first to Fi s. 1 to 4 inclusive, it will be seen. that the closet: is formed'as a one-piece structure, with the various ducts and water-ways therein. f j N The bowl proper. is denoted generally by 1, and surmount'sa base or pedestal 2. The vent duct isdesignated by 3, the inner portion whereof opens directlyinto the bowl and under the diminished rear segment of ries an inside oval, as to the bow-l rim, of

12 inches for its long diameter. I To secure anti-soiling features to the rim it has heretoforebeen deemed necessary to distort the oval and abruptly enlarge the rear section of the oval by receding same in a semi-squared portionof lesser or greater width in order to not disturb the usual method of feeding the rim from the rear.

In other cases the rim oval has been carried back for one inch to a point in order that the usual rim feed wouldhave'water way of sufiicient capacity. Other. methods of receding the rim, such as raisingsame above the regular plane of the top and undercutting same, have been used, but in all cases the regularity-of the rim has been destroyed and the maximum of non-soil not achieved. v

By my method of construction I'have secured a true oval to the rear on a long diameter of 13 inches-thus, with the seat attachment remaining fixed, I have removed the entire rim one inch to the rear and receiving thereby the maximum non-soil angle across theedge of the seat opening and flushing rim. This idea is not broadly claimed'herein as the same forms the subjectmatter of my copending application Serial No. 181,069 filed on or about the 17th day of July 1920.v

To the rear of the seat hinge-post holes 7, duct 3'extends upwardly and rearwardly, terminating in a mouth or spigot 8. Pockets 9 are provided in the side walls of the closet,

open and free throughout its length betweenthe bowl and the stack towhich it is connected; -Such an arrangement of the vent duct, and the reconstruction of the rear portion of the flushing rim 5 necessitates a rearrangement of the Water ducts and passages.

The-water supply from the usual tank or reservoir-enters the regulartop inlet or conduit 10 from which extend branches or ways 11,which pass downwardly and slightly forward and open inwardlyinto a chamber or recess'12 underlying the bottom-of the'trap and provided with thefusual jet orifice or open ng 13. Each of the-vertically-disposed ways 11 is in communication with a horizontally disposed way 14;, the forward end of which turns upwardly, as at 15, and

opens into the adjacent flushing-rim from below at a point on either side of the closet just forward of a rear segment of the rim,

oval containing the diminished water way shown by Figs. 1 and 3 and made'necessary by my construction tosecure the full oval rim withinallowedfspace.

A' plurality of openings'16 will preferably be provided through the wall between the upper portion of the vent 3, and the conduit 10, to thoroughly fiush-orw'a'sh down the walls of the vent duct at each operation of the closet. i

The trap and siphon outlet of the closet are denoted by 17 and; 18, which latter terminates in the usual outlet nozzle 19. I

From :the foregoing it is thought that the advantages accruing'from the construcother construction. J

tion I will appear to those skilled in the art, but it may be well to set them forth in a eneral way. W

eretofore, vent ducts have been made integral with the closet and connected to '70 the 'bowl by means of one or more openings extending through the bowl wall and under the 'edgejof the continuous flushing rim, producing an uncleanable pocket back of the bowl surface and out ofreach of the flushing water. A

Withfthe construction above set forthI am enabled to provide alocal or rear Vent which has a clear and free opening extending from the bowl to the stack and which in a closet of standard dimensions may be of full four-inch diameter. Furthermore, the duct is kept below the rim of the. closet bowl until well beyond. the point of seat attachment, thus taking the rear raised por-, tion of the vent well out of the way of the user.

- Also, by reason of the placing of the bowl outlet passage or trap farther to the rear than usual, I secure a greater volume of 90 water in thebowl and trap and a proportionally greater resistance to the passage of sewergas' i 'When no local vent exists or is needed,

the vent duct may be omitted, and the other I V structural features and their inherent advantages retained. Such a construction is disclosed vin-Fig. 5 and inasmuch as the vent ductis alone omitted the. other parts aredenoted by the same referencenumerals as in the otherfigures x The receded full oval sanitary rim, the covered seat post boxes or pockets, and the above water-level feed. to therear ends of the flushing rim are'all present. Thereceded rear portion :of the-bowl surface, denoted by 20, whichextends up to the pockets or'boxes 9,.is washeddown by the water passing from theopenings 16, asunder the"v .While the design of-a closet around the novedfeatures which I-have introduced seeminglyadmits of but little change, still it isevidentthat closets of types other than,

of the siphon .jet class may; be similarly produced, and I do not, therefore, wish to be understood as limiting myself thereto.
